A local service business offers quick repairs and larger installation projects. Repairs produce frequent, inexpensive enquiries. Projects generate fewer leads, cost more to acquire and take longer to close.
Should those services share one Google Ads campaign?
The answer depends on the business economics and the controls required. A separate campaign can protect a service budget or support different goals. A shared campaign can be simpler and avoid unnecessary fragmentation when the services genuinely have compatible requirements.
Start by identifying what a lead is worth and what the account can reliably measure.
Compare contribution rather than job revenue
A large invoice is not automatically a more profitable job. Materials, fulfilment labour, delivery, subcontractors and other variable costs can change the result.
For planning, use a consistent definition of contribution before advertising cost. Document which costs it includes and keep it separate from net profit.
This is a hypothetical example. The amounts are illustrative dollars, not market benchmarks.
| Service | Contribution per completed job, before ad cost | Close rate from qualified leads | Estimated contribution per qualified lead |
|---|---|---|---|
| Small repair | $100 | 40% | $40 |
| Larger project | $1,000 | 10% | $100 |
The last column multiplies contribution by the estimated close rate. It is an expected planning value, not a realised profit figure.
If both services generate qualified leads at $30 each, the same headline cost per lead represents different economics. If the larger-project leads cost $90, they are not automatically better simply because the invoice is larger.
The calculation also depends on stable qualification and close-rate estimates. A few recent wins are not enough to assume a durable 10% closing rate.
Establish whether the leads are actually comparable
Before changing campaign structure, review how each service records its funnel.
A repair might be booked immediately. A project may need a site visit, a quotation and several follow-ups. Comparing this week's repair bookings with this week's new project enquiries can make the project campaign appear worse simply because its outcomes mature later.
Record the service requested, enquiry date, qualification result, sales stage and eventual outcome. Use a reporting window that accommodates the relevant sales cycle.
Where lead definitions or attribution disagree, resolve those issues first. Campaign structure cannot compensate for a report that treats an unanswered phone click as equivalent to a qualified project enquiry.
Separate campaigns when a real control is needed
Splitting becomes useful when the business needs to control something at campaign level.
| Business requirement | Why separation may help |
|---|---|
| Reserve a budget for a strategic service | A dedicated campaign can have its own budget, provided it is not placed in an unsuitable shared budget |
| Serve different areas or schedules | Campaign settings can reflect different operational requirements |
| Use materially different conversion goals | Each service can use goals suited to its measurable outcome |
| Protect limited fulfilment capacity | Spending can be managed against the service's available slots |
| Apply a distinct acquisition strategy | Bidding and reporting can be aligned with different commercial objectives |
Do not split solely because one keyword costs more than another. First show that the separation gives the business a useful control or a cleaner customer journey.
Also check overlapping targeting and routing. Separate campaigns with unclear ownership of the same intent can make management more complicated.
Keep services together when the requirements align
A shared campaign can be reasonable when the services have compatible locations, schedules, offers and goals, and the business does not need separate spending commitments.
Relevant ad groups and landing pages may be enough to distinguish intent without creating another campaign. The business still needs service-level lead and sales reporting.
Google generally recommends account-default conversion goals for learning across campaigns, while supporting campaign-specific goals when the business needs them. Its guidance also points to conversion values as a way to distinguish outcomes with different business value.1
That means “different lead value” does not automatically equal “different campaign.” The practical decision includes value measurement, control needs and the amount of useful data available.
Decide what values the account should receive
There are several possible approaches:
- Record enquiries and evaluate commercial outcomes outside the bidding system while measurement is improved.
- Record properly defined qualified-lead stages, using supported integrations.
- Supply defensible estimated lead values or completed-outcome values where the implementation and data quality support them.
Do not attach a large, arbitrary number to project enquiries just to force the account toward them. Review close rates, contribution estimates and how values are updated.
Keep the treatment of funnel stages consistent. Counting enquiry, qualification and sale values as separate additive outcomes can overstate the business value if the intended calculation represents one sale.
Value-based optimisation works with the values supplied to the platform. It does not independently calculate the business's true margin.
Test the structure with a written decision rule
Before a restructure, write down:
“The current setup cannot protect project capacity and budget separately. We will separate the project service, preserve clear intent routing and compare qualified leads and mature sales outcomes using consistent definitions.”
Or:
“The services have the same operating constraints. We will keep the campaign together, improve service-level reporting and test whether better value information supports the desired mix.”
Record what is changing and the date. Avoid combining the restructure with an unrelated landing-page rewrite and major budget expansion if you need to understand the result.
Make the decision around the service mix
The useful outcome is a sustainable mix of work, not the lowest blended cost per lead.
A Google Ads account review should connect structure to capacity, contribution and lead quality. If strong dashboard returns coexist with weak business results, high ROAS and low profit is the next issue to examine.
